A Wasp Landed On My Car Then Vomited Up Some Water?

It re-swallowed the water after this photo. Would anyone happen to know why it would have done that?

I just know houseflies sometimes do it with what is kinda their spit to pick up food, but wasps have a totally different mouth made for killing bugs and even knawing wood for their paper nests
- Don't flies regurgitate onto their food to help pre-digest it? I learned this from that fabulous documentary, The Fly.
I wouldn’t know, I’d be too busy looking for my flamethrower..
